Real-World Use Cases
====================

MailTrigger is solving real problems in production. Here are three real-world examples:

Travel Alerts Without API Hassles
---------------------------------

A family trip to Japan inspired a real-time flight alert system. Instead of integrating with LINE’s API, the script routed alerts through MailTrigger by email — which then pushed LINE notifications instantly.

Scenarios of Using MailTrigger
==============================

.. note::

   The following are just a few example use cases to spark ideas—MailTrigger supports many more real-world scenarios beyond these.


Real-Time Alerts from DevOps Tools
----------------------------------

Your company uses **Jenkins** to assist with deployments.
When a deployment or build fails, Jenkins by default can only send emails.

However, most developers do not frequently check emails, causing build failure messages to be **missed** or **delayed**.

**MailTrigger solves this problem**:

- Jenkins continues sending build result messages via email.
- If you set up **routes for LINE and WhatsApp** in MailTrigger,
  these messages can be delivered directly to your messaging apps.

This ensures **real-time visibility** for the team.

----

Add New Channels Without Changing Your Code
-------------------------------------------

Bob is a software developer at Company A.
The platform he is developing sends **weekly emails** to subscribed users—but only via email.

His supervisor now requests support for **Discord** and **WhatsApp** message delivery in addition to emails.

Implementing this separately for each platform would be **time-consuming**.

Instead, Bob uses **MailTrigger** to:

- Add **routes and rules** for LINE and WhatsApp on his domain.
- Keep using the **same email-sending function** in his application.

Result: messages are now sent to **Email + Discord + WhatsApp**, without writing any extra messaging integration logic.

----

Forward Emails from Gmail to Messaging Apps
-------------------------------------------

You can use other email services (e.g., **Gmail**) to **forward emails** to your MailTrigger mailbox.
Once received, MailTrigger will automatically apply the configured **routes** to forward the content.

**Example use case**:

- Bob wants to read "CNN News" emails from his Gmail on **WhatsApp**.
- He sets up a Gmail forwarding rule that sends those emails to `Bob@example.com`.
- MailTrigger receives them and forwards the content to WhatsApp.

This makes it **easier and faster** for Bob to read his news updates.
